Professor Marsden is a chemistry teacher at Hillside High School.

Physical appearance

He is a Caucasian malewith brown hair. He wears a light blue lab coat with a light brown shirt underneath and a brown tie.


He's very strict about teaching, that he disapproved of the students having any fun, thinking they should do schoolwork.

He's also quite a grouch as he ordered Daphne and Scrappy to leave the computer lab without an explanation.


The New Scooby and Scrappy Doo Show

The gang asked him if he knows anything about the Creature from Chem Lab, but denies any knowledge. He was pleased when the school dance was cancelled because of the Creature.

He saw Daphne and Scrappy in the computer lab, and without Daphne explaining, takes the video game that was dropped by the creature, and ordered them to leave.

He showed up when Toby Wallace was caught, and lectured him saying he'd better find a way to pay all the damages he caused.

At the dance he was disturbed about Scooby's new dance he made up.
